APPARATUS FOR-DEI-IYDRATING TAR.

Application led May 20,

This invention relatesto a method and apparatus for dehydrating tar.V

The object of the invention is to utilize a steam jet which atomizes the tar emulsion, carrying oif the water and allowing the tar to fall by gravity to the point of accumulation. l A further object is to provide an apparatus of the character, stated in which a tank is employed for receiving a tar emulsion and from which the emulsion is drawn and atomized by a steam jet, the steam carrying oii the moisture and the tar permitted to re` turn to the bottom of the tank.

A. further object is to supply an apparatus of this character from which the dehydrated tar may be drawn after the operation is completed.

With these and other objects in view the v invention consists in certain novel features of construction and combinations and arrangements of parts, which will be more fully hereinafter described and pointed out in the claims. In the accompanying drawings- Figure l is a view, mainly in longitudinal section but partly in elevation, illustrating my improved apparatus;

Figure 2 is a view in longitudinal section through the steam jet.

l represents a tank in which a tar emul sion 2 is deposited. 4 represents a pipe coupling having four nipples. A vertical pipe 5 communicates with the lower nipple 1 35 of the coupling 4 and has a ff-head `6 at its lower end adjacent the bottom of the tank 1. 7 represents an emulsion lifting steam jet having a supply steam pipe 8 communieating therewith, with a cock 9 controlling the passage of steam. This jet 7 is connected by a pipe 10 with one of the nipples lof the pipe coupling 8, and a discharge pipe 11 is connected to theopposite nipple of said coupling 4.

Vrlhe upper nipple of the coupling 4 is normally closed by a removable plug l2, but when the plug is removed a tar withdrawal pipe 18 may be, attached to the coupling, as i indicated by dotted linesV in Figure l. 14

bottom of the et 7 and extends down into the tank l the desired distance.

After the tar emulsion is deposited in the tank l a separation of the tar and water will take place by gravity.

The operation of the apparatus and method is as follows:

The cock 9 is opened and the passage of steam through the jet 7 will draw the emulsion up through pipe 14 and discharge it through pipe 10. The tar being heavier and more sluggish than the water or steam will pass down the pipe 5 and the water will flow through the pipe 11 to anydesired outlet. rihis operation is Vrepeated until the dehydrating process is ended, when the plug l2 is removed. The pipe 13 connected to the coupling 4 will draw off the tar to a tank or other depository.

It is this broad idea of the utilizing` of a steam jet for dehydrating tar emulsion which constitutes the broad idea of my invention, and while l have illustrated what l believe to be a preferred embodiment of my invention it is obvious that various changes and alterations might be made in the general form of the parts described without departing from niy invention and hence l do not limit myself to the precise details set forth but consider' myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.
